Note 1: The first four paragraphs come from the translation available in the "making of the OST" included in the game's OST (PS2Game- Hajimari no Tabi Gakudan). I changed them a tiny bit, because they were missing some words.

Note 2: There are many lines being sung in the background, but there's no lyrics for them. I tried my best to recognize the English lyrics.
(Sung in the background)
*1 And today a new adventure comes,
it gets tainted (jp=somaru) ever more.
*2 And we will get through.
*3 You and I will be as one.
*4 You are so beautiful. You said that I'm beautiful. And I'll receive all that you have for me.
